Due to the increasing small size and higher performance of information equipment and advances in electronic information technology such as digitization of information, a variety of signal processing apparatuses, data recording/reproducing apparatuses, communication apparatuses, information processing apparatuses, etc. have spread in use. These apparatuses have come to make frequent use of positional information in recent years.

For example, by storing positional information of facilities and locations originating certain data, positional information of locations acquiring certain data, etc. linked with the data, there are the effects that when later using the data, it becomes easier to use the data, it becomes possible to use the data in a new form, etc. Thus, data has come to be used in a variety of venues.

More specifically, it is being used for clearly indicating locations of post offices or restaurants along with information thereof, for indicating shooting locations for photos and other image data, etc.

This positional information is numerical data such as latitude and longitude and in itself is hard for people to directly understand, grasp, and use.

Therefore, in many cases the data is used by the method of using some sort of pointer or mark on map information to indicate the position.

For this, each apparatus has to hold the map information in advance.

However, there was the problem that this map information was generally a large amount of data and it was difficult for all apparatuses to hold the information. Particularly, it has been substantially difficult to store and hold such a large amount of map information in mobile terminals, camcorders, and other small sized equipment. As a result, there is the problem that positional information cannot be used in the most suitable form in apparatuses not holding map information.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be explained with reference to FIG. 1 to FIG. 7.

In the present embodiment, the present invention will be explained by taking as an example a video camcorder system capable of picking up and storing a desired video and image and displaying already stored video and images on a liquid crystal screen, particularly a video camcorder system capable of displaying image data, stored linked with positional information, linked with map information.

First, the configuration of the video camcorder system will be explained with reference to FIG. 1.

FIG. 1 is a block diagram of the configuration of a video camcorder system 100.

The video camcorder system 100 has a video camcorder 110, a memory stick 140, and a mobile phone 150.

The video camcorder 110 has an optical system 111, an image signal processing unit 113, a control circuit 115, an operation button unit 125, and an LCD 131. Further, the control circuit 115 has a CPU 117, a bus 119, a ROM 121, a RAM 123, an operation unit 127, an LCD controller 129, an IF unit 133, a network controller 135, and an MS-IF unit 137.

Below, the configurations of the components will be explained.

The optical system 111 picks up a desired video or image and outputs a corresponding signal. The optical system 111 has an optical system for forming an image of a desired image on the surface of a pickup element, a drive unit for driving the optical system, a pickup element for generating an electric signal corresponding to the formed image, etc.

The image signal processing unit 113 performs predetermined signal processing on the signal output from the optical system 111 to convert it to an image signal of a predetermined format and outputs it to the control circuit 115. Specifically, the image signal processing unit 113 processes the input image signal for analog/digital conversion, white balance, gamma correction, etc. and encodes the result to a predetermined format to generates an image signal of a predetermined format.

The control circuit 115 comprises the main signal circuits of the video camcorder 110 on a semiconductor integrated circuit and controls portions of the video camcorder 110 so that processing such as picking up a desired image, storing the taken image, reproducing and displaying the stored image, acquiring relating map information, and displaying the acquired map information is suitably performed in the video camcorder 110.

As explained above, the control circuit 115 has a CPU 117, bus 119, ROM 121, RAM 123, operation unit 127, LCD controller 129, IF unit 133, network controller 135, and MS-IF unit 137.

The CPU 117 further controls the components of the control circuit 115 so that the control circuit 155 realizes the above functions.

Specifically, first the CPU 117 controls the IF unit 133, bus 119, MS-IF unit 137, etc. to store a picked up image and video by reading a picked up image and video signal from the image signal processing unit 113 via the IF unit 133 and storing the same in the memory stick 140 or a not shown other storage medium via the MS-IF unit 137.

Further, the CPU 117 controls the MS-IF unit 137, bus 119, LCD controller 129, etc. to reproduce and display the stored image by reading a positional information file and an image signal from the memory stick 140 or not shown other storage medium via the MS-IF unit 137 and displaying it on the LCD 131 via the LCD controller 129.

Further, the CPU 117 controls the MS-IF unit 137, bus 119, network controller 135, LCD controller 129, etc. to display the positional information file of the stored image data on a map by reading the positional information file from the memory stick 140 or the not shown storage medium via the MS-IF unit 137, suitably detecting a reference of map information stored in the positional information file, acquiring the map information via the mobile phone 150, and displaying the acquired information on the LCD 131.

Further, the CPU 117 controls the operation unit 127, bus 119, MS-IF unit 137, etc. to reproduce and display the stored image based on the map information by detecting operation of the operation button unit 125 by the user via the operation unit 127 and reading the desired image signal based thereon from the memory stick 140 or the not shown storage medium via the MS-IF unit 137.

Further, the CPU 117 controls the processing for generating a positional information file at the time of storing a picked up image or video in accordance with need. In this case, the CPU 117 first detects a position of the video camcorder 110 based on GPS received information received at a not shown GPS receiver provided in the video camcorder 110 in accordance with need. Then, the CPU 117 uses the positional information and information indicating a location of map information to be referred to set in advance to generate a positional information file and stores the same along with the picked up image data in the memory stick 140 via the MS-IF unit 137.

The CPU 117 for example performs control relating to such processing.

Note that the content and format of the positional information file will be explained in detail later.

The bus 119 is a system bus in the video camcorder 110 for connecting the CPU 117 and components.

The ROM 121 is a memory for storing a processing program for executing above explained processing, parameters referred to by the components at that time, etc.

The RAM 123 is a memory for storing data generated by the CPU 117 and components, data being processed, etc. at the time of executing such processing in the same way.

The operation button unit 125 is an operation means operated by a user of the video camcorder 110. Instructions to pick up and reproduce an image, to select image data from map information, etc. are given via the operation button unit 125.

The operation unit 127 detects an operation of the operation button unit 125 by a user, generates a signal based on the content of the operation, and outputs the same to predetermined components such as the CPU 117 or LCD controller based on the content of the operation.

The LCD controller 129 is a controller for displaying on the LCD 131 image data or map information input via the bus 119.

The LCD 131 is a liquid crystal display controlled by the LCD controller 129 and displaying input desired image data.

The MS-IF unit 137 is an interface controlled by the CPU 117 and communicating with the memory stick 140. Storage of image data and a positional information file to the memory stick 140 or reading of the image data and a positional information file from the memory stick 140 are performed via the MS-IF unit 137.

Specifically, the MS-IF unit 137 communicates with the memory stick 140 via three signal lines of a first signal line (SCLK) for sending a clock, a second signal line (SDIO) for transferring data, and a third signal line (SS) for sending a status.

The memory stick 140 is a detachable card type storage medium loaded in the video camcorder 110. In the video camcorder 110 of the present embodiment, it particularly stores a positional information file including information indicating a position of image data and reference information of map information and is accessed in accordance with need.

The configuration of the memory stick 140 will be explained in detail with reference to FIG. 2.

The memory stick 140 has a control IC 141, flash memory 142, and write protect switch 143. The control IC 141 has a serial/parallel parallel/serial (S/P•P/S) interface sequencer 144, page buffer 145, flash interface sequencer 146, ECC encoder/decoder 147, register 148, and attribute ROM 149.

The S/P•P/S interface sequencer 144 of the control IC 141 communicates with the MS-IF unit 124 of a navigation apparatus 110, receives a clock signal SCLK and a status signal SS, and transfers data SDIO.

More specifically, it receives data SDIO sent from the navigation apparatus 110 and converts it to parallel data in synchronization with a serial clock SCLK, then outputs the converted data to the register 148 when a command while outputs it to the page buffer 145 when data.

Further, it converts data sent to the navigation apparatus 110 input from the page buffer 145 etc. to serial data and sends it to the navigation apparatus 110 via a data line SDIO.

The page buffer 145 of the control IC 141 is a memory for storing data input from the control IC 141 in page units (512 bytes). Data stored in the page buffer 145 is, after being given an error correction code by the ECC encoder/decoder 147, stored in the flash memory 142 via the flash interface sequencer 146.

Further, the page buffer 145 stores data read from the flash memory 142 via the flash interface sequencer 146. Then, after corrected for error in the ECC encoder/decoder 147, the data is suitably output to the S/P•P/S interface sequencer 144.

The flash interface sequencer 146 stores data in page units stored in the page buffer 145 in the flash memory 142 in accordance with need or reads data stored in the flash memory 142 in page units and stores it in the page buffer 145.

The ECC encoder/decoder 147 adds an error correction code to data stored in the page buffer 145 to be stored in the flash memory 142. Further, it corrects error for data stored in the page buffer 145 and read from the flash memory 142.

The register 148 generates a control command based on command data input from the S/P•P/S interface sequencer 144. For example, when the register 148 receives a read status register command for checking an operating state of the memory stick 140, it detects content set in the write protect switch 143 and sets the set content to the register. Then, it sends the content of the register to the navigation apparatus 110 via the S/P•P/S interface sequencer 144.

The attribute ROM 149 is a memory storing version information, initial settings, and other information of the memory stick 140. The information of the initial settings stored in the attribute ROM 149 is read based on a control command generated in the register 148 the first time that the memory stick 140 is loaded in the navigation apparatus 110 and is used for setting the parts in the memory stick 140.

The flash memory 142 is a storage unit for actually storing a positional information file and additional information.

The write protect switch 143 is a switch for limiting writing of data to the flash memory 142 so as not to delete data stored in the memory stick 140.

The mobile phone 150 is an ordinary mobile phone, but is used as a communication apparatus for communicating with any communication node in the video camcorder system 100. The mobile phone 150 performs desired communication in accordance with a request from the CPU 117 by being connected to the control circuit 115 of the video camcorder 110 via the network controller 135. As processing according to the present invention, this is used to access the Internet to acquire map information from a desired node.

Next, a positional information file stored in the memory stick 140 will be explained with reference to FIG. 3 to FIG. 5.

First, the basic configuration of the positional information file will be explained with reference to FIG. 3.

FIG. 3 is a view of a first specific example of the positional information file.

In the positional information file shown in FIG. 3, lines 1 to 3 are a description for clarifying and setting a descriptive format of the positional information file. In the positional information file shown in FIG. 3, it is set here that the file is in a format using XML (eXtensible Markup Language).

The “format” tag in lines 4 to 7 describes the used positioning system, coordinate system, information creator, information creation date and time, etc.

The “gpoi” tag in lines 8 to 17 is a description defining the specific position. In the present embodiment, it is used for indicating a position where image data corresponding to the positional information file was picked up.

The “index” tag in line 9 is a search tag describing positional information having a latitude and longitude, information indicating the type of the position, information indicating whether the position is a moving object, the positioning system, etc.

Further, the position is actually defined in the “poi” tag in lines 11 to 17. Here, the latitude is specified by the “lat” tag in line 13, while the longitude is specified by the “lon” tag in line 14.

The “linkfile” tag in lines 18 to 20 describes information for specifying data relating to the position, that is, information for specifying image data corresponding to the positional information file.

The “mapset” tag in lines 21 to 25 is a tag for specifying the reference when an apparatus does not include map information and refers to external map data.

The “mapset” tag describes a “getmap” tag indicating a link to one or more map information and a “comment” tag for writing a comment described in accordance with need.

The “getmap” tag is written in a format as shown in (1). <getmap format=“file format” size=“image size” href=“hyper reference></getmap>  (1)

As shown in the format (1), the “getmap” tag describes the three attributes of “format”, “size”, and “href”.

The attribute “format” is for clearly indicating the format of map data to be linked by URI and can designate the JPEG, GIF, PNG, BMP, SVG and other formats.

The attribute “size” describes the image size of the map data by a decimal number like [Size=“xxxx yyyy”] (xxxx: number of horizontal pixels, yyyy: number of vertical pixels).

The attribute “href” indicates the URL of the map data to be linked. Particularly, the map data to be linked has to be a map in a range which can be pointed to in position by the “poi” tag.

In the description of lines 21 to 25 of the positional information file in FIG. 3, the “format” attribute is “JPEG” and “160 120” is designated as the “size” attribute. Accordingly, it is learned that a 160 pixel X 120 pixel JPEG format file is specified. Further, the “href” attribute specifies the file on a network.

Next, the configuration of the positional information file describing the linkage of the map information and actual position in a “getmap” tag will be explained with reference to FIG. 4.

FIG. 4 is a view of a second specific example of a positional information file. This is a file of a format describing an “upper-right” tag and a “lower-left” tag after the “getmap” tag on a line 22 of the positional information file shown in FIG. 3.

The “upper-right” tag is a description of information indicating the position of the upper right portion of the map information, while the “lower-left” tag is a description of information indicating the position at the lower left portion of the map information. The “lat” tag and “lon” tag describe the latitude and longitude, respectively.

By using such a description method, that is, by describing the “upper-right” tag and the “lower-left” tag in a positional information file, the map information no longer has to include information for specifying the position. As map information capable of specifying a certain position, what position a region described as a map indicates needs to be indicated for example by the latitude and longitude. This is normally described in the header of the map information. By using such a descriptive method, however, such information becomes unnecessary. As a result, general map information can be used as the map information of the reference.

As the positional information file, a file of the above format can be used.

Next, a positional information file having a plurality of “getmap” tags will be explained with reference to FIG. 5.

FIG. 5 is a view of a third specific example of a positional information file, wherein “getmap” tags are described in lines 22 to 24 and lines 25 to 27 from the “mapset” tag of line 21 on. More specifically, a link to map information of the JPEG format is described in lines 22 to 24 and a link to map information in the PNG format is described in lines 25 to 27.

The positional information file, as explained above, can describe two or more “getmap” tags.

In this case, on the apparatus side such as on a video camcorder 100 side using the above, it is sufficient to select and use a map of a format or size in accordance with the apparatus, objective, etc.

Also, depending on the case, after acquiring a plurality of map information, it is possible to perform processing prompting a user to make a selection etc.

By using such a description method, it becomes possible to describe a positional information file supporting a plurality of apparatuses.

As a positional information file, a file of such a format can be used.

Next, the operation of the video camcorder system 100 will be explained with reference to FIG. 6, FIG. 7A, and FIG. 7B.

Note that, here, the operation of the video camcorder system 100 according to the present invention of first displaying map information for image data stored along with the positional information file and displaying image data superimposed on the map information by selection from the screen will be explained.

FIG. 6 is a flow chart for explaining such an operation of the video camcorder system 100.

First, when a user tries to operate the apparatus as explained above, the CPU 117 searches for a positional information file to be displayed from the flash memory 142 of the memory stick 140 via the MS-IF unit 137 based on a predetermined operation by the user (step S10).

Next, it searches for a “getmap” tag from the file (step S11). When there is no “getmap” tag, it cannot display a map and cannot display the position on a map, so for example performs processing for displaying the positional information by text on the LCD 131 (step S12).

When there is a “getmap” tag, it checks whether there are a plurality of “getmap” tags (step S13). When there are a plurality, it checks whether there is map information able to be displayed in it based on content of the “getmap” tags (step S14). When there is map information able to be displayed, it further searches for the most suitable map information in it (step S15). When there is no “getmap” tag which defines map information able to be displayed in the plurality of “getmap” tags (step S14), it cannot display a map and cannot display the position on a map, so for example it performs processing for displaying the positional information by text on the LCD 131 (step S17).

Also, when there is only one “getmap” tag in the positional information file (step S13), it checks whether the map information is able to be displayed based on the content of the “getmap” tag (step S16). When the map information cannot be displayed, it cannot display a map either so for example performs processing for displaying the positional information by text on the LCD 131 (step S17)

When suitable map information able to be displayed is detected in the plurality of “getmap” tags at step S15 or when one “getmap” tag is map information able to be displayed at step S16, the CPU 117 acquires map information from a link described in the “getmap” tag via the mobile phone 150 (step S18).

Then, it displays the map information on the LCD 131 and makes some mark at the location specified by the positional information file to clearly indicate the position.

By performing such processing, even a video camcorder system 100 not having map information therein can, for example as shown in FIG. 7A, display map information 200 on the LCD 131. Further, it can display the positional information of specific data on the map information 200 for example in the form of a mark 201.

Note that in the video camcorder system 100 performing such processing, for example by the user selecting the mark 201, the CPU 117 can read data linked with the positional information, that is, image data, from the memory stick 140 and display it on the LCD 131.

For example, when superimposed on the map information 200, the image data 203 is displayed as shown in FIG. 7B.

Note that the present invention is not limited to the present embodiment. Any various preferable modifications can be made.

For example, the above embodiment uses a mobile phone 150 as a communication means for connecting a network and the video camcorder system 100. However, the communication means is not limited to the mobile phone 150. Any communication apparatus can be used.

Further, the above embodiment illustrated as an example a system using a video camcorder, but the present invention is not limited to this. It can be applied to any apparatus not having map information therein.

Further, the above embodiment stores the positional information file and image data in the memory stick 140, but this does not has to be a memory stick. Any portable type of storage medium will do. It is also possible to store the file and data in a not shown storage unit in the video camcorder system 100.

In this way, according to the present invention, it is possible to provide an information processing apparatus and an information processing method enabling effective utilization of any data including positional information by linking the positional information with map information even if not having map information internally.

Further, it is possible to provide a machine readable storage medium storing control information of an information processing apparatus enabling effective utilization of any data including positional information by linking the positional information with map information even in an information processing apparatus not having map information internally.

Still further, it is possible to provide an image processing apparatus enabling effective utilization of image data linked with positional information by linking it with map information even if not having map information internally.
